MACHINE FOB., JOINTING STAVES.

Specification of Letters Patent No. 10,683, dated March 21, 1854. i

To all fr0/1,0m t may concern Be it known that I, ALEXANDER WILBUR, ofLancaster, in the county of Lancaster and State of Pennsylvania, haveinvented certain new and useful Improvements in Machines for JointingStaves; and I do hereby declare the following to be a full, clear, andexact description of the same, reference being had to the accompanyingdrawings, making a part thereof, in which- Figure 1 represents a sideView of the machine; and Fig. 2, a vertical section through the centerlof the swing frame, with a portion of the concave dressing wheel.

Similar letters in both figures denote like parts.

' The nat-ure of my invention relates to the method of joint-ing stavesof variable widths, each with its requisite bilge, without adjusting themachine, it having a self-operating adjustment for each andevery width.Also in combination with the swing frame in which the stave is presentedto the cutter wheel, the guides which move with it, for the purpose ofholding the edge of the stave being dressed firmly to the wheel ofcutters.

4To enable othersskilled in the art to make and use my invention, I willproceed to describe the same in connection with the drawings. v

The frame A, may be constructed inany well known substantial manner, soas to sup port a cutter wheel B, on a vertical shaft C, provided with apulley D, over which a belt from any first mover may pass. The top faceof the cutter wheel B, is concave and provided with any required numberof cutters E, E, &c. At one side of the frame I arrange a swing frame F,into which the stave is placed to be presented to the cutter wheel. Thestaves arey not bent or sprung in the swing frame but lie perfectlystraight, the concavity of the jointing wheel giving it the properbilge. The swing frame F, has an axis or journal a which has no fixedbearing, but moves in a slot c, which is on the same plane with`theconcave surface of the jointing wheel.

Z is a shoulder, and e, a lip or projection on the end of the swingframe against and under which the stave is held, against 'the action lofthe cutters, the distance between.

the axis a, of the swing frame, and the f pointl where the stave isheld, being one half i v the `diameter of t-he `barrel for whichv the=stave isbeing dressed. A rod f, runs across the back of the swing framepermanently attached thereto, and the ends of this rod or bar pass intoinclined staples or slots g, one at each side of the frame (though onelonly is seen in the drawings); and behind the swing frame is a springIt, to throw it for- Ward and raise it up to receive or remove thestave. A bar z', one at each side of the swing frame is attached to theaxis or rod a, and is made to slide in grooves cut in the pieces G, ofthe frame, and tothe ends of these bars z' are arranged two cross barsjyj, beveled off on their opposite faces, vand just far enough apart toadmit the edge of the stavevto `be dressed, and prevent its moving inany other direction than vertically while being operated on. As theseguide bars are connected to and move withthe swing frame,

they will be in place to receive any stave coming in to be dressedwhether wide or It will be perceived from the description that thereneed be no waste of material, precontinues to descend, the rod f, in thein-` clined staples g, draws back the swing frame, the slot c admittingthe axis a of the said frame to move back in the plane of the wheel,constantly changing the point of action on the concave, so that whetherthe stave be wide or narrow it has its requisite bilge, without any lossof material.

Having thus fully described the natu-re of my invention, what I claimtherein as new, and desire to secure by Letters Patent, is-

1, SO hanging the swing frame, which feeds up the :stave t0 the jntngWheel, as to the Ontng Wheel or cutters substantially that staves ofvariable Wfdths may be (lressd as described.

with thebilve necessary or said Wdt ssl f stantally ase described.ALEXANDER WILBUR' .5Y 2. I alsov claim in combination With theVWitnesses:

swing frame the guides which move with it, A. B. STOUGHTON, for thepurpose of firmly holding` the stave l SAML. GRUBB.
